Low halogen and halogen-free low smoke flame retardant polyolefin wires and cables have the same electric properties as PVC insulated wires and cables. Its flame retardant properties comply to the requirement of GB****6.*****0 (identical to IEC ****3 bundle burning ). For low halongen cables the quantity of the halogen acid is less than **0mg/g, For halogen-free low smoke flame retardant polyolefin wires and cables, the quantity of the halogen acid is less than 5mg/g. The smoke density complies to GB****6.*****0(identical to IEC ****4 burning chamber test method). For low halogen cable the smoke density is larger than *0%. For halogen-free low smoke cables the smoke density is larger than *0%.The cables have the same dimensions as PVC insulated cables. For low halogen cables the insulation should be halogen-free low smoke polyolefin or PE or XLPE. For low halogen cables the inner and outer sheath should be low smoke polyolefin sheath material. For halogen-free low smoke cables the inner sheath should be low halogen low smoke or halogen-free low smoke polyolefin smoke polyolefin sheath material, the outer sheath should be halogen-free low smoke polyolefin material. For anti-termite cables the sheath should be anti-termite halogen-free low smoke sheath material.
